SITUATION OVERVIEW
------------------

At 100 PM CDT (1800 UTC), the center of Hurricane Laura was located
near latitude 27.3 North, longitude 92.5 West. Laura is moving toward
the northwest near 16 mph (26 km/h) and a gradual turn toward the
north-northwest and north is expected later today into tonight. On the
forecast track, Laura will approach the Upper Texas and southwest
Louisiana coasts this evening and move inland within that area tonight.

Laura has intensified to an extremely dangerous category 4 hurricane with maximum
sustained winds of 140 mph. Laura will arrive as a major category 4
hurricane at landfall tonight. Expected maximum storm surge values
will be at least 15 to 20 feet. This will result in life threatening
inundation. Evacuate immediately if you are within an area where this
extreme surge may occur. Also a significant surge will occur up the
lower Neches, Sabine, Calcasieu, Mermentau, and Vermilion River basins.

Heavy rain producing bands of showers and a few thunderstorms will
continue to move inland the rest of the afternoon as Laura continues
its northwest approach, then expand northward overnight as Laura moves
inland. A moderate to high risk of flash flooding will result. Isolated
tornadoes will also be possible across the area.

Tropical storm force winds are expected to spread across southwest
Louisiana the rest of the afternoon and southeast Texas this evening.
Hurricane force winds, especially in frequent gusts, will be likely
beginning Wednesday night across southwest Louisiana and southeast
Texas continuing into Thursday morning up into upper southeast Texas
and west central Louisiana.

POTENTIAL IMPACTS
-----------------

* WIND:
Protect against life-threatening wind having possible devastating
impacts across southwest Louisiana and southeast Texas. Potential
impacts in this area include:
    - Structural damage to sturdy buildings, some with complete roof
      and wall failures. Complete destruction of mobile homes. Damage
      greatly accentuated by large airborne projectiles. Locations
      may be uninhabitable for weeks or months.
    - Numerous large trees snapped or uprooted along with fences and
      roadway signs blown over.
    - Many roads impassable from large debris, and more within urban
      or heavily wooded places. Many bridges and access routes
      impassable.
    - Widespread power and communications outages.

* SURGE:
Protect against life-threatening surge having possible catastrophic
impacts across lower southwest Louisiana and southeast Texas.
Potential impacts in this area include:
    - Widespread deep inundation, with storm surge flooding greatly
      accentuated by powerful battering waves. Structural damage to
      buildings, with many washing away. Damage greatly compounded
      from considerable floating debris. Locations may be
      uninhabitable for an extended period.
    - Escape routes and secondary roads washed out or severely
      flooded. Flood control systems and barriers may become stressed
      or overtopped.
    - Extreme beach erosion. New shoreline cuts possible.
    - Massive damage to marinas, docks, and piers. Numerous small
      craft broken away from moorings with many lifted onshore and
      stranded.

* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
extensive impacts across southwest Louisiana and southeast Texas.
Potential impacts include:
    - Major rainfall flooding may prompt many evacuations and rescues.
    - Rivers and tributaries may rapidly overflow their banks in
      multiple places. Small streams, creeks, canals, and ditches may
      become dangerous rivers. Flood control systems and barriers may
      become stressed.
    - Flood waters can enter many structures within multiple
      communities, some structures becoming uninhabitable or washed
      away. Many places where flood waters may cover escape routes.
      Streets and parking lots become rivers of moving water with
      underpasses submerged. Driving conditions become dangerous.
      Many road and bridge closures with some weakened or washed out.

* TORNADOES:
Protect against a tornado event having possible limited impacts across
southwest Louisiana and southeast Texas. Potential impacts include:
    - The occurrence of isolated tornadoes can hinder the execution
      of emergency plans during tropical events.
    - A few places may experience tornado damage, along with power
      and communications disruptions.
    - Locations could realize roofs peeled off buildings, chimneys
      toppled, mobile homes pushed off foundations or overturned,
      large tree tops and branches snapped off, shallow-rooted trees
      knocked over, moving vehicles blown off roads, and small boats
      pulled from moorings.

PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------

* EVACUATIONS:
Listen to local official for recommended preparedness actions,
including possible evacuation. If ordered to evacuate, do so
immediately.

For those not under evacuation orders, assess the risk from wind,
falling trees, and flooding at your location. If you decide to move,
relocate to a safer location nearby. If you do not relocate, help keep
roadways open for those under evacuation orders.

If evacuating, leave with a destination in mind and allow extra time
to get there. Take your emergency supplies kit. Gas up your vehicle
ahead of time.

Let others know where you are going prior to departure. Secure loose
items and pets in the car, and avoid distracted driving.

If evacuating, follow designated evacuation routes. Seek traffic
information on roadway signs, the radio, and from official sources.

* OTHER PREPAREDNESS INFORMATION:
Now is the time to complete all preparations to protect life and
property in accordance with your emergency plan. Ensure you are in a
safe location before the onset of strong winds or possible flooding.

If you are relocating to safe shelter, leave as early as possible.
Allow extra time to reach your destination. Many roads and bridges
will be closed once strong winds arrive. Check the latest weather
forecast before departing and drive with caution.

If heading to a community shelter, become familiar with the shelter
rules before arrival, especially if you have special needs or have
pets. Take essential items with you from your Emergency Supplies Kit.

Failure to adequately shelter may result in serious injury or loss of
life. Always heed the advice of local officials and comply with any
orders that are issued. Remember, during the storm 9 1 1 Emergency
Services may not be able to immediately respond if conditions are
unsafe. This should be a big factor in your decision making.

It is important to remain calm, informed, and focused during an
emergency. Be patient and helpful with those you encounter.

If you are a visitor, be sure to know the name of the city or town in
which you are staying and the name of the county or parish in which
it resides. Listen for these locations in local news updates. Pay
attention for instructions from local authorities.

Storm surge is the leading killer associated with tropical storms and
hurricanes! Make sure you are in a safe area away from the surge
zone. Even if you are not in a surge-prone area, you could find
yourself cutoff by flood waters during and after the storm. Heed
evacuation orders issued by the local authorities.

Rapidly rising flood waters are deadly. If you are in a flood-prone
area, consider moving to higher ground. Never drive through a flooded
roadway. Remember, turn around don't drown!

If a Tornado Warning is issued for your area, be ready to shelter
quickly, preferably away from windows and in an interior room not
prone to flooding. If driving, scan the roadside for quick shelter
options.

If in a place that is vulnerable to high wind, such as near large
trees, a manufactured home, upper floors of a high-rise building, or
on a boat, consider moving to a safer shelter before the onset of
strong winds or flooding.

Closely monitor weather.gov, NOAA Weather radio or local news outlets
for official storm information. Be ready to adapt to possible changes
to the forecast. Ensure you have multiple ways to receive weather
warnings.
